BitmapData.alphaMask can now also take a Phaser.Sprite, Phaser.Image or BitmapData object as a source type.

Browse source 
BitmapData.alphaMask has 4 new optional parameters: x, y, x2 and y2 to control exactly where the source and mask images are drawn.

### Updates
* BitmapData.draw can now take a BitmapData object as a source type.
* BitmapData.draw can now also take a Phaser.Sprite, Phaser.Image or BitmapData object as a source type. As a result BitmapData.drawSprite is now depcreated.
* BitmapData.alphaMask can now also take a Phaser.Sprite, Phaser.Image or BitmapData object as a source type.
* BitmapData.alphaMask has 4 new optional parameters: x, y, x2 and y2 to control exactly where the source and mask images are drawn.
